The era of multi-gigabit automotive Ethernet: TE is ready for the connector you need!

Today's automotive industry is rapidly evolving towards electrification, networking, intelligence and sharing. In this process, innovative applications such as autonomous driving, smart infotainment and vehicle networking are constantly being introduced into the mobile "smart device" of the car. In order to carry these ever-increasing new functions and efficiently process and transmit the massive data generated, the upgrade and reconstruction of the vehicle network is imperative.

In-vehicle Ethernet is an important driving force for the transformation of in-vehicle network technology. It can provide sufficient bandwidth for current ADAS, audio and video entertainment, networking and other applications, and has the potential to support higher-performance applications in the future. At present, more and more automakers are promoting the development and application of multi-gigabit (10Gbps+) data link design architectures, and the corresponding high-performance and high-reliability connector products have become the key to supporting ultra-high-speed data transmission and meeting the current and next-generation gigabit in-vehicle Ethernet and parallel converter applications.
